G-QS-150 Replacement Sterilight QS-150 Quartz Sleeve for SP150-HO & SPV-2.5

Maintain the efficiency and reliability of your UV water treatment system with the G-QS-150 Replacement Quartz Sleeve, a premium compatible replacement for the Sterilight QS-150. Manufactured from high-quality fire-polished fused quartz, this sleeve provides exceptional UV light transmission while protecting the UV lamp from direct contact with water.

Designed for Sterilight SP150-HO and SPV-2.5 UV systems, this compatible quartz sleeve features a closed (domed) end and is supplied complete with two replacement O-rings for a secure, leak-free installation.

Over time, mineral deposits such as limescale, iron and manganese can build up on the quartz sleeve, reducing UV light transmission and lowering the effectiveness of your UV disinfection system. Regular cleaning and scheduled replacement help ensure your UV system continues to provide maximum protection against bacteria, viruses and other microorganisms.
